Screening for anxiety, depression, and anxious depression in primary care: A field study for ICD-11 PHC

Machine learning-ready mental health datasets for evaluating psychological effects and system needs in Mexico city during the first year of the COVID-19 pandemic

The prevalence of mental health problems constitutes an open challenge for modern societies, particularly for low and middle-income countries with wide gaps in mental health support. With this in mind, five datasets were analyzed to track mental health trends in Mexico City during the pandemic's first year. This included 33,234 responses to an online mental health risk questionnaire, 349,202 emergency calls, and city epidemiological, mobility, and online trend data. The COVID-19 mental health risk questionnaire collects information on socioeconomic status, health conditions, bereavement, lockdown status, and symptoms of acute stress, sadness, avoidance, distancing, anger, and anxiety, along with binge drinking and abuse experiences. The lifeline service dataset includes daily call statistics, such as total, connected, and abandoned calls, average quit time, wait time, and call duration. Epidemiological, mobility, and trend data provide a daily overview of the city's situation. The integration of the datasets, as well as the preprocessing, optimization, and machine learning algorithms applied to them, evidence the usefulness of a combined analytic approach and the high reuse potential of the data set, particularly as a machine learning training set for evaluating and predicting anxiety, depression, and post-traumatic stress disorder, as well as general psychological support needs and possible system loads.

Mistakes are not an option: aggression from peers and other correlates of anxiety and depression in pediatricians in training

Introduction

Pediatricians in training are a population at risk for anxiety and depression: they face long working hours, they are confronted with the suffering and death of a vulnerable population and may have personal characteristics that put them in danger. Nonetheless, few studies have looked at their prevalence and associated factors. We aimed to compare demographic, professional activities, adversities and perfectionism personality features between a group of pediatricians in training with depression and/or anxiety and a group of pediatricians in training without depression nor anxiety and, to identify the variables that increase the probabilities of depression and/or anxiety in pediatricians in training.

Methods

Pediatric residents who voluntarily answered an online survey distributed via personal and institutional social media channels from October 2019 to April 2021, as part of a cross-sectional study with medical specialists and residents from Mexico were included. Demographic information, professional activities and adversities, perfectionism personality features (Multidimensional Perfectionism Scale), depression and anxiety (ICD-11 PHC) were evaluated. For comparison purposes Chi-square tests (χ2) and independent sample t-tests were used. A logistic regression analysis was used to identify those variables that increase the probabilities of depression and/or anxiety.

Results

934 pediatric residents answered the survey. 11.6% reported having depression and 20% anxiety. Being single, a history of anxious or depressive episodes, being the resident in charge of a patient who died, aggressions from colleagues and a high concern for errors were associated with current depression and/or anxiety.

Discussion

Screening for depressive and anxious symptoms should be routinely performed from entry to the residency to favor early intervention. A shift from promoting perfectionism to a more compassionate training could serve a population facing so many adversities.

To the bone: Prevalence and correlates of depression and anxiety among orthopedic residents in Mexico

OBJECTIVE

Examining orthopedic residents in Mexico, researchers explore the relationship between the presence of depressive or anxious symptoms and the degree of perfectionism, perceived work-related distress, and involvement in the care of patient(s) who died.

METHODS

This was a cross-sectional online survey of 642 orthopedic residents from October 2019 to April 2021.

RESULTS

Of orthopedic residents contacted, 50.6% responded rate (70.9% male, average age 29.8 years). A total of 12.5% reported significant depressive symptoms and 18.4% reported significant anxious symptoms. On a scale from 0-100, the mean score of perceived work-related distress was 51.9. One-third (33.6%) reported being involved in the care of patient(s) who had died. Higher levels of work-related distress and higher scores on perfectionism were associated with depressive and anxiety symptoms. In particular, being involved in the care of patient(s) who had died was associated with anxious symptoms (OR = 1.79; 95%CI = 1.18-2.72).

CONCLUSIONS

These results highlight the need for systematic monitoring of the mental health of orthopedic residents in Mexico, particularly those who report a high level of work-related distress or perfectionism or who have recently experienced the death of a patient.

Improving patient-centered mental health promotion in primary care in vulnerable communities through mindfulness training in Rio de Janeiro, Brazil

Introduction

Brazilian Primary Health Care (PHC) is responsible for all-sanitary actions for a community-based population, including health promotion and mental health care. Mindfulness Based Health Promotion (MBHP) is an intervention that can promote self-care and psychosocial support in PHC.

Objective

To discuss the effects of mindfulness based psychosocial group interventions for health promotion in primary care units in Rio de Janeiro, Brazil.

Methods

The intervention was based on the MBHP model adapted for SUS. Nine groups were held in Rio de Janeiro. A quali-quanti research was held with two parts: (a) quantitative study, pre and after the 8 weeks intervention, evaluating the effect on mindfulness and self-compassion and their association with levels of anxiety, depression, and quality of life. (b) Qualitative research using Focus Groups with the participants to investigate their experience at the end of the mindfulness groups.

Results and discussion

Sixty-two participants finished the 9 groups where 86% were women, mostly between 30 and 59 years of age and low income, and around 80% under regular medical care in PHC in SUS. In the studied sample 80% had at least one chronic health condition under treatment, including 42% with anxiety and 35% with depression. The effects included significant improvement in Anxiety and Depression and in Quality of Life, mainly in the psychological but also in the physical and interrelation domains. The qualitative study showed that most patients joined the group on the recommendation of health professionals for managing physical and mental health symptoms. Patients reported being able to use the practices taught in the sessions to manage symptoms such as insomnia and emotionally distressing situations in their daily lives. Including family members in mindfulness practices was a strategy to negotiate not only a space at home to meditate, but also to obtain a different approach to health problems. Participants pointed to mindfulness as a complementary therapeutic option to medication and psychotherapy.

Conclusion

Mindfulness-Based Intervention have shown to be a feasible, well-accepted and efficacious method of offering psychosocial support and promoting well-being for low-income patients in primary care in LAMIC.

Pathways of depressive symptoms to self-harm and suicide warning signs during COVID-19 pandemic: The role of anxiety and related distress, dysfunction and somatization

BACKGROUND

Early in the COVID-19 pandemic, concern about widespread waves of depression and suicide emerged worldwide. Clarity on the relationship between mental health symptoms and warning signs of current self-harm or suicide thoughts and behaviors (ShSTB) in Mexican adults could be useful for designing effective public health policies and preventive strategies during health emergencies.

OBJECTIVE

The present study uses a path model to explore the relationship between depressive symptoms, anxiety, and related distress, dysfunction, and somatization with ShSTB warning signs in Mexican adults during the COVID-19 pandemic. The study also describes the relative risks of these mental health variables for men and women, and for those who were seeking psychological care versus those who were not.

METHOD

The study was conducted with 18,449 Mexicans (M = 33 years, SD = 11.00, range = 18-59), including 12,188 women (66.10 %) and 2706 (14.67 %) who were seeking psychological care. A web-based application included two multidimensional screening scales to evaluate depression, anxiety and somatic symptoms and related distress/dysfunction, as well as past and current ShSTB. Based on the participants' sex, the entire sample was randomly divided into two sub-samples to compare and replicate the Confirmatory Factor Analysis (CFA) results, getting evidence of the multidimensionality of the scales. With the two sub-samples, we also tested the nested models from a structural equation model (SEM) to suggest a relationship between mental health and self-harm/suicide variables.

FINDINGS

Our findings suggest that 31 % of participants were at risk for depression, 42.30 % for anxiety, 38.30 % for Marked Distress, Dysfunction and Somatization (MDDS), 33.30 % for at least one ShSTB, and 4.20 % for Previous Self Harm Thoughts and Behaviors (PShTB) during the COVID-19 pandemic. A greater percentage of women and participants seeking psychological care showed high levels of mental health symptoms, PShTB, MDDS, and ShSTB. The path model suggested a direct influence of PShTB and MDDS on ShSTB. Depression symptoms lead to ShSTB in three possible ways: through PShTB, PShTB affecting MDDS, and generalized anxiety affecting MDDS.

DISCUSSION AND OUTLOOK

The pandemic was accompanied by a high prevalence of depression-anxiety, marked distress, dysfunction and somatization and self-harm/suicide thoughts and behaviors. The findings of this study suggest evidence over the well-known association between depression and anxiety, and between depression, previous self-harm thoughts and behaviors, and self-harm/suicide. The evidence suggests to distinguish when participants were suffering from MDDS and anxious depression from those only suffering from depression. The methodological conditions of the study suggest a comprehensive model of ShSTB prevention. Findings also suggest the need to care for Mexicans with depressive symptoms and PShTB as well as those suffering from anxious depression with MDDS to prevent suicide, by implementing effective public health policies and preventive strategies to reduce the mental health gap during health emergencies.

LIMITATIONS

This research was a cross-sectional study, suggesting that future analyses should focus on the evaluation of its consistency with confirmed diagnoses of mental health disorders, self-harm/suicide risks, and the effect of remote psychological help to address these problems.

A Systematic Review of the Psychometric Properties of the Patient Health Questionnaire-4 in Clinical and Nonclinical Populations

BACKGROUND

The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief instrument that measures depressive and anxiety symptoms. Although it has been frequently used in the last 15 years, no research has systematically reviewed its psychometric properties.

OBJECTIVE

This systematic review summarized, for the first time, the available published evidence on the psychometric properties of the PHQ-4.

METHODS

This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and was registered in the Prospective Register of Systematic Reviews, under the identification code CRD42022381809. The search strategy was applied in Medline, PsycINFO, Web of Science, and SCOPUS from 2009 (year of publication) to 2023 (present). Two independent reviewers performed screening, data extraction, and methodological quality assessment of the studies. The data was reported through a narrative synthesis.

RESULTS

In total, 26 studies involving 93,466 participants from 19 countries, with clinical and nonclinical samples, were included. The two-factor structure was the most frequent, being invariant according to gender, age, geographic location, income, educational level, and language. The internal consistency was adequate for distress (α from 0.72 to 0.88), as well as for depression (α from 0.65 to 0.81) and anxiety (α from 0.74 to 0.84). The temporal stability of the instrument was verified through test-retest reliability, reporting an acceptable connection between both measures. Correlations with related measures were significant and in the expected direction.

CONCLUSIONS

The PHQ-4 is a reliable and valid instrument for screening depressive and anxiety symptoms, both for the clinical and nonclinical populations. Due to the brevity of its administration, the PHQ-4 could be a clinical tool that contributes to optimizing health resources.

Interpersonal and Intimate Violence in Mexican Youth: Drug Use, Depression, Anxiety, and Stress during the COVID-19 Pandemic

The COVID-19 pandemic may have increased interpersonal and intimate violence, harmful use of alcohol and other drugs (AODs), and mental health problems. This study uses a valid path model to describe relationships between these conditions of young Mexicans during the second year of the pandemic. A sample of 7420 Mexicans ages 18 to 24-two-thirds of whom are women-completed the Life Events Checklist, the Alcohol, Smoking, and Substance Involvement Screening Test, the Major Depressive Episode Checklist, the Generalized Anxiety Scale, and the Post-traumatic Stress Disorder (PTSD) Checklist. Young Mexicans reported higher rates of victimization and perpetration of interpersonal and intimate violence and mental health symptomatology than those noted pre- and in the first year of the pandemic. The harmful use of AOD rates were similar to those reported by adolescents before. The findings suggest asymmetric victimization and perpetration of intimate violence by gender (with women at a higher risk). More men than women have engaged in the harmful use of AODs (except for sedatives, which more women abuse). More women than men were at risk of all mental health conditions. The path model indicates that being a victim of intimate violence predicts the harmful use of tobacco, alcohol, cocaine, and sedatives, depression, anxiety, and specific PTSD symptoms (such as re-experimentation and avoidance symptoms). Being a victim of interpersonal violence resulted in severe PTSD symptoms (including avoidance, negative alterations in cognition-mood, and hyperarousal signs). The harmful use of sedatives predicted depressive symptoms. Men's victimizing intimate violence model contrasted with that of women, which included being the victim of interpersonal violence and severe PTSD symptoms. The high school youth model had three paths: victimizing intimate violence, victimizing interpersonal abuse, and sedative use, which predicted depression. Our findings could serve as the basis for future studies exploring the mechanisms that predict violence to develop cost-effective preventive programs and public policies and to address mental health conditions during community emergencies.

Gender Differences in Professional Adversities and Mental Health Among Surgical and Nonsurgical Medical Trainees: An Internet-Based Survey

BACKGROUND

Physicians in training face a variety of stressors throughout their professional development and according to their gender. Among them, surgical trainees appear to be especially at risk for mental health problems.

OBJECTIVE

The aim of the present study was to compare demographic features, professional activities and adversities, depression, anxiety, and distress among men and women trainees of surgical and nonsurgical medical specialties.

DESIGN AND PARTICIPANTS

A cross-sectional, retrospective, comparative study was conducted on a total of 12,424 trainees (68.7% nonsurgical and 31.3% surgical) from Mexico through an online survey. Demographic features, variables related to professional activities and adversities, depression, anxiety, and distress were evaluated through self-administered measures. Comparative analyses using the Cochran-Mantel-Haenszel test for categorical variables and multivariate analysis of variance including medical residency program and gender as fixed factors to test their interaction effect for continuous variables were used.

RESULTS

An important interaction between medical specialty and gender was found. Women trainees from surgical specialties report more frequent psychological and physical aggressions. Women from both specialties had higher distress, significant anxiety, and depression than men. Men from surgical specialties worked more hours per day.

CONCLUSIONS

Gender differences are evident in trainees for medical specialties, with a larger impact in surgical fields. Mistreatment of students is a pervasive behavior that affects society as a whole, and actions to improve learning and working environments in all medical specialties, but mostly in surgical fields, are urgently needed.

Prevalence and associated factors of common mental disorders in primary care settings in Sofala Province, Mozambique

BACKGROUND

In Mozambique, the prevalence of common mental illness in primary care is not well established.

AIMS

This study aimed to assess the prevalence of, and associated factors for, common mental illness in patients accessing primary care services in three Ministry of Health clinics in Mozambique.

METHOD

Adult patients were recruited from the waiting rooms of prenatal, postpartum and general out-patient consultations. A mental health professional administered a diagnostic interview to examine prevalence of major depressive disorder (MDD), generalised anxiety disorder (GAD), post-traumatic stress disorder (PTSD) and any substance misuse or dependence. Generalised linear mixed models were used to examine the odds of each disorder and sociodemographic associations.

RESULTS

Of 502 patients interviewed, 74.1% were female (n = 372) and the average age was 27.8 years (s.d. = 7.4). Of all participants, 23.9% (n = 120) met diagnostic criteria for at least one common mental disorder; 8.6% were positive for MDD (n = 43), 13.3% were positive for GAD (n = 67), 4.8% were positive for PTSD (n = 24) and 4.0% were positive for any substance misuse or dependence (n = 20). Patients attending prenatal or postpartum consultations had significantly lower odds of any common mental disorder than patients attending out-patient primary care. Age was negatively associated with MDD, but positively associated with substance misuse or dependence.

CONCLUSIONS

Over 20% of patients attending primary care in Mozambique may have common mental disorders. A specific focus on patients attending general out-patient visits, young people for depression, and older people and men for substance misuse/dependence would provide a targeted response to high-risk demographics.

Public perception of social workers as a source for providing help during the COVID-19 pandemic

Summary

The current study examined the contribution of select demographic and psychosocial variables, as well as prior experience with social workers (SWs), to explaining the likelihood of seeking their help by the general public in Israel during the COVID-19 pandemic. For the purpose of the study, an online questionnaire was administered to a sample of 582 respondents older than 20.

Findings

The findings show that the respondents reported a fairly low likelihood of seeking help from SWs. Women, those not in a significant relationship, people who had prior experience with SWs, and those reporting higher levels of loneliness, had a higher likelihood of seeking help from SWs. At the same time, no association was found between age, employment status, depression, and anxiety, and the likelihood of seeking help from SWs.

Applications

When dealing with the mental, health, and social consequences of the COVID-19 crisis, it is important to identify groups with a lower likelihood of seeking help from SWs and to actively offer them help. Furthermore, it is important to develop a policy aimed at promoting knowledge of SW roles and reducing barriers to seeking SW help, while attending to the unique needs of diverse population groups.

Measurement invariance of the GAD-5 Generalized Anxiety Disorder Scale in a Mexican general population sample

The primary objective of this study was to evaluate the measurement of invariance by sex, age, and educational level of an online version of the Generalized Anxiety Disorder Scale in a five-item version (GAD-5). Configural, metric, scalar, and strict invariance were evaluated using data from 79,473 respondents who answered a mental health questionnaire during the COVID-19 pandemic in Mexico. The sex variable was classified as male or female; age was categorized as minors, youth, young adults, adults, and older adults; and educational level was divided into basic, upper secondary, higher, and graduate education. To test for configural invariance, confirmatory factor models were constructed. For metric invariance, equality restrictions were established for the factor loadings between the construct and its items; for scalar invariance, equality restrictions were established between the intercepts; strict variance implied the additional restriction of the residuals. Statistical analysis was performed in R software with the lavaan package. The results show that with respect to sex, age, and educational level, configural and metric measurement invariance was confirmed (ΔCFI < 0.002; ΔRMSEA < 0.015). However, with respect to scalar and strict invariance, the results showed significant differences regarding the fit model (ΔCFI > 0.002; ΔRMSEA > 0.015). We conclude that the GAD-5 presents configural and metric invariance for sex, age, and educational level, and scalar invariance for sex and age groups. However, the scale does not demonstrate strict invariance. We discuss the implications and suggest that this result could be related to the evaluation of sociodemographic variables.

Depressive, Anxious, and Post-Traumatic Stress Symptoms Related to Violence during the COVID-19 Pandemic, by Sex, COVID-19 Status, and Intervention-Seeking Conditions among the General Population

Worldwide, three out of four of the general population have reported experiencing violence. Governments should address solutions to violence and its effects on mental health. The study aimed to determine depressive, anxious, and posttraumatic stress symptoms related to the violence experienced during the COVID-19 pandemic in the general population. The study was conducted with 18,449 Mexicans of 33 years (SD = 11.00, range = 18-59), with 12,188 (66.10%) being women, 3559 (19.29%) having COVID-19, 2706 (14.67%) seeking psychological care, and 5712 (30.96%) experiencing violence. Subjects completed the Major Depressive Episode (MDE) Checklist, Generalized Anxiety (GA) Scale, and the Posttraumatic Stress (PTS) Checklists (PCL-5) programmed in a WebApp application. We assessed the dimensionality of the scales through the Confirmatory Factor Analysis (CFA), the measurement invariance, and a structural equation model (SEM). In the total sample, 28.10% fulfilled the MDE criteria, and 42.30% had high levels of GA. In the sample of those experiencing violence, 48.40% met the MDE criteria, 61.70% had high GA symptoms, and 50% met the criteria for a PTS disorder. Experiencing violence was associated with GA and severe PTS symptoms when the discomfort had bothered them for over a month since the onset of these symptoms. Subjects who had experienced violence and had mental health symptoms seemed ready for treatment. Further studies will evaluate the effect of remote psychological care to help reduce the treatment gap.

Implementation Science of Telepsychotherapy for Anxiety, Depression, and Somatization in Health Care Workers Dealing with COVID-19

Introduction: Cognitive behavioral therapy (CBT) has proven to be effective in treating affective and somatic symptoms, which are among the leading mental health problems of health care workers (HCWs) dealing with COVID-19 (HCW-COVID-19). However, efforts to develop and evaluate the strategies required to promote its implementation in clinical practice are still scarce, particularly in low- and middle-income countries. Objective: To describe and evaluate the implementation process and clinical impact of a brief, remote, manualized CBT-based intervention for moderate anxiety, depressive, and somatic symptoms among Mexican HCW-COVID-19 ≥18 years old. Methods: The implementation process comprises community engagement, intervention systematization and education, leadership engagement, and team-based coaching as main strategies. A total of 26 participants completed self-report measures of symptoms before and after treatment, and a subsample of 21 answered a final questionnaire on the acceptability of the intervention. Therapists registered the techniques used in each case, regardless of whether they were part of the intervention manual. Results: The number of sessions was 4.6 (2.43). The most frequently employed techniques were those included in the intervention manual, especially identifying and modifying maladaptive thoughts, used to treat 70% of HCW-COVID-19. Supplementary techniques were implemented to enhance treatment or meet HCW-COVID-19s special needs (such as workplace issues, insomnia, COVID-19 status, and bereavement). The intervention had a significant effect (delta Cohen's coefficients ≥1), and the majority of HCW-COVID-19 were "totally satisfied" with its contents and considered it "not complex" (95.2% and 76.1%, respectively). Conclusions: Telepsychotherapy for anxiety, depression, and somatization in HCW coping with health emergencies in middle-income countries is a feasible, clinically valuable, and acceptable form of treatment.

Brief Screening for Distress among Healthcare Professionals: Psychometric Properties of the Physician Well-Being Index—Spanish Version

Background: The Physician Well-Being Index (PWBI) is a brief, valid, reliable self-assessment instrument to identify health professionals’ distress and those in need of an intervention. Objective: to evaluate the construct, predictive validity (of depression, suicidal ideation, insomnia, and generalized anxiety), and internal consistency of the 7-item Spanish version of the PWBI (PWBI-S). Methods: out of a national population of approximately 1 million Mexican healthcare professionals, a sample of 3506 subjects (42.0% physicians, 28.7% nurses and 29.3% psychologists) completed an online survey between 17 April and 7 May 2020, at the time of the COVID-19 case cluster transmission scenario in Mexico. Results: In the three sub-samples, PWBI-S’s Confirmatory factor analyses (adding residual covariances) exhibited adequate goodness of fit indices for the PWBS original unidimensional model. Overall Cronbach’s alphas were 0.89 for physicians, 0.90 for nurses, and 0.86 for psychologists. Univariate logistic regression models showed that a cutoff point of 3 on the total score of the PWBI-S was generally related to the presence of depression, suicidal ideation, and insomnia, but not with generalized anxiety among nurses and psychologists. When trying with a cutoff point of 3, a relationship with GA was shown in psychologists, but not in nurses. Conclusions: our findings suggest that PWBI-S is a valid, reliable measure for clinical and research purposes in the field.

Screening Tool for Mental Health Problems During COVID-19 Pandemic: Psychometrics and Associations With Sex, Grieving, Contagion, and Seeking Psychological Care

Background

The COVID-19 pandemic has created a public mental health crisis. Brief, valid electronic tools are required to evaluate mental health status, identify specific risk factors, and offer treatment when needed.

Objective

To determine the construct validity, reliability, and measurement invariance of a brief screening tool for mental health symptoms by sex, loss of loved ones, personal COVID-19 status, and psychological care-seeking during the COVID-19 pandemic. Furthermore, the aim involved establishing a predictive pattern between the mental health variables.

Method

A total sample of 27,320 Mexican participants, with a mean age of 32 years (SD = 12.24, range = 18–80), 67% women (n = 18,308), 23.10% with a loss of loved ones (n = 6,308), 18.3% with COVID-19 status (n = 5,005), and 18.40% seeking psychological care (n = 5,026), completed a questionnaire through a WebApp, containing socio-demographic data (sex, loss of loved ones, COVID-19 status, and psychological care-seeking) and the dimensions from the Posttraumatic Checklist, Depression-Generalized Anxiety Questionnaires, and Health Anxiety-Somatization scales. We used the confirmatory factor analysis (CFA: through maximum likelihood to continuous variable data, as an estimation method), the invariance measurement, and the structural equational modeling (SEM) to provide evidence of the construct validity of the scale and the valid path between variables. We analyzed the measurement invariance for each dimension by comparison groups to examine the extent to which the items showed comparable psychometric properties.

Findings

The tool included eight dimensions: four posttraumatic stress symptoms -intrusion, avoidance, hyperactivation, and numbing, as well as depression, generalized anxiety, health anxiety, and somatization The tool’s multidimensionality, was confirmed through the CFA and SEM. The participants’ characteristics made it possible to describe the measurement invariance of scales because of the participants’ attributes. Additionally, our findings indicated that women reported high generalized anxiety, hyperactivation, and depression. Those who lost loved ones reported elevated levels of intrusion and health anxiety symptoms. Participants who reported having COVID-19 presented with high levels of generalized anxiety symptoms. Those who sought psychological care reported high levels of generalized anxiety, intrusion, hyperactivation, and health anxiety symptoms. Our findings also show that intrusion was predicted by the avoidance dimension, while health anxiety was predicted by the intrusion dimension. Generalized anxiety was predicted by the health anxiety and hyperactivation dimensions, and hyperactivation was predicted by the depression one. Depression and somatization were predicted by the health anxiety dimension. Last, numbing was predicted by the depression and avoidance dimensions.

Discussion and Outlook

Our findings indicate that it was possible to validate the factor structure of posttraumatic stress symptoms and their relationship with depression, anxiety, and somatization, describing the specific bias as a function of sociodemographic COVID-19-related variables. We also describe the predictive pattern between the mental health variables. These mental health problems were identified in the community and primary health care scenarios through the CFA and the SEM, considering the PCL, depression, generalized anxiety, health anxiety, and somatization scales adapted during the COVID-19 pandemic. Therefore, future studies should describe the diagnosis of mental health disorders, assessing the cut-off points in the tool to discriminate between the presence and absence of conditions and mental health cut-off points. Community and primary care screening will lead to effective early interventions to reduce the mental health risks associated with the current pandemic.

Limitations

Future studies should follow up on the results of this study and assess consistency with diagnoses of mental health disorders and evaluate the effect of remote psychological help. Moreover, in the future, researchers should monitor the process and the time that has elapsed between the occurrence of traumatic events and the development of posttraumatic stress and other mental health risks through brief electronic measurement tools such as those used in this study.

Using Artificial Intelligence to Enhance Ongoing Psychological Interventions for Emotional Problems in Real- or Close to Real-Time: A Systematic Review

Emotional disorders are the most common mental disorders globally. Psychological treatments have been found to be useful for a significant number of cases, but up to 40% of patients do not respond to psychotherapy as expected. Artificial intelligence (AI) methods might enhance psychotherapy by providing therapists and patients with real- or close to real-time recommendations according to the patient's response to treatment. The goal of this investigation is to systematically review the evidence on the use of AI-based methods to enhance outcomes in psychological interventions in real-time or close to real-time. The search included studies indexed in the electronic databases Scopus, Pubmed, Web of Science, and Cochrane Library. The terms used for the electronic search included variations of the words "psychotherapy", "artificial intelligence", and "emotional disorders". From the 85 full texts assessed, only 10 studies met our eligibility criteria. In these, the most frequently used AI technique was conversational AI agents, which are chatbots based on software that can be accessed online with a computer or a smartphone. Overall, the reviewed investigations indicated significant positive consequences of using AI to enhance psychotherapy and reduce clinical symptomatology. Additionally, most studies reported high satisfaction, engagement, and retention rates when implementing AI to enhance psychotherapy in real- or close to real-time. Despite the potential of AI to make interventions more flexible and tailored to patients' needs, more methodologically robust studies are needed.

Mental Health Problems among COVID-19 Frontline Healthcare Workers and the Other Country-Level Epidemics: The Case of Mexico

COVID-19 frontline healthcare workers (FHCW) are struggling to cope with challenges that threaten their wellbeing. We examine the frequency and predictors of the most frequent mental health problems (MHP) among FHCW during the first COVID-19 peak in Mexico, one of the most severely affected countries in terms of FHCW’s COVID-19 mortality. A cross-sectional survey was conducted between May 8 and August 18, 2020. A total of 47.5% of the sample (n = 2218) were FHCW. The most frequent MHP were insomnia, depression, posttraumatic stress symptoms, and health anxiety/somatization (whole sample: 45.7, 37.4, 33.9, and 21.3%; FHCW: 52.4, 43.4, 40.3 and 26.1, respectively). As compared to during the initial COVID-19 phase, depression and health anxiety/somatization symptoms as well as experiences of grieving due to COVID-19, personal COVID-19 status, and having relatives and close friends with COVID-19 were more frequent during the COVID-19 peak. Obesity, domestic violence, personal COVID-19 status, and grieving because of COVID-19 were included in regression models for main FHCW’s MHP during the COVID-19 peak. In conclusion, measures to decrease other country-level epidemics contributing to the likelihood of COVID-19 complications (obesity) and MHP (domestic violence) as well as FHCW´s probability of COVID-19 infection could safeguard not only their physical but also mental health.

Modulation of Auditory Perception Laterality under Anxiety and Depression Conditions

The objective of this work is to confirm the asymmetry in non-linguistic auditory perception, as well as the influence of anxiety-depressive disorders on it. Eighty-six people were recruited in the emotional well-being group, fifty-six in the anxiety group, fourteen in the depression group, and seventy-seven in the mixed group. In each group, audiograms were obtained from both ears and the differences were statistically analyzed. Differences in hearing sensitivity were found between both ears in the general population, such differences increased in people with anxiety-depressive disorders. When faced with anxiety-depressive disorders, the right ear suffered greater hearing loss than the left, showing peaks of hyper-hearing at the frequency of 4000 Hz in the anxiety subgroup, and hearing loss in the depression subgroup. In relation to anxiety, the appearance of the 4:8 pattern was observed in the right ear when the person had suffered acute stress in the 2 days prior to the audiometry, and in both ears if they had suffered stress in the 3–30 days before said stress. In conclusion, the advantage of the left ear in auditory perception was increased with these disorders, showing a hyperaudition peak in anxiety and a hearing loss in depression.

A global field study of the international classification of diseases (ICD-11) mood disorders clinical descriptions and diagnostic guidelines

BACKGROUND

We report results of an internet-based field study evaluating the diagnostic guidelines for ICD-11 mood disorders. Accuracy of clinicians' diagnostic judgments applying draft ICD-11 as compared to the ICD-10 guidelines to standardized case vignettes was assessed as well as perceived clinical utility.

METHODS

1357 clinician members of the World Health Organization's Global Clinical Practice Network completed the study in English, Spanish, Japanese or Russian. Participants were randomly assigned to apply ICD-11 or ICD-10 guidelines to one of eleven pairs of case vignettes.

RESULTS

Clinicians using the ICD-11 and ICD-10 guidelines achieved similar levels of accuracy in diagnosing mood disorders depicted in vignettes. Those using the ICD-11 were more accurate in identifying depressive episode in recurrent depressive disorder. There were no statistically significant differences detected across classifications in the accuracy of identifying dysthymic or cyclothymic disorder. Circumscribed problems with the proposed ICD-11 guidelines were identified including difficulties differentiating bipolar type I from bipolar type II disorder and applying revised severity ratings to depressive episodes. Clinical utility of ICD-11 bipolar disorders was found to be significantly lower than for ICD-10 equivalent categories.

LIMITATIONS

Standardized case vignettes were manipulated to evaluate specific changes. The degree of accuracy of clinicians' diagnostic judgments may not reflect clinical decision-making with patients.

CONCLUSIONS

Alignment of the ICD-11 with current research appears to have been achieved without sacrificing diagnostic accuracy or clinical utility though specific training may be necessary as ICD-11 is implemented worldwide. Areas in which the ICD-11 guidelines did not perform as intended resulted in further revisions.

Community-Based Mental Health Services in Mexico

AIM

This article describes the general characteristics of community-based mental healthcare in Mexico.

METHODS

Data from national surveys, special studies and statistics from the national information system during the period 2001-2017 are used. Available information on health systems, new regulations and the innovations implemented are reviewed, as well as research on psychosocial interventions conducted within the country.

RESULTS

Data show a fragmented health system with services for workers and those without social security or private care. This is a treatment system essentially based on tertiary healthcare and not integrated into the general health system, with a significant treatment gap and delay in relation to the first treatment. At the same time, a slow but steady increase in the level of care provided at primary healthcare level and in specialized community services has been observed. This trend has been accompanied by an increase in the number of medical doctors, psychologists and, to a lesser extent, psychiatrists, incorporated into the primary healthcare services. At the same time, no new psychiatric hospitals have been built; there has been a proportional reduction in psychiatric beds but no increase in mental health services or beds allocated to first contact hospitals. Research initiatives have analysed the barriers to reform, and efficient interventions have been developed and tested for the community and for primary healthcare; special interventions are available for the most vulnerable but no formal efforts have been to facilitate their implementation.

CONCLUSIONS

Evidence is available regarding the implementation of the transition from reliance on tertiary healthcare to reinforced primary care. At the same time, parity, financial protection, quality and continuity of care remain major challenges.

Mental Health Symptoms, Binge Drinking, and the Experience of Abuse During the COVID-19 Lockdown in Mexico

Background: The health crisis associated with the COVID-19 pandemic is causally linked to negative mental health symptoms in the same way as other diseases such as Ebola.

Objective: The purpose of this paper is to describe the relationship between mental health symptoms, binge drinking, and the experience of abuse during the COVID-19 lockdown.

Method: We surveyed 9,361 participants, all Mexican, with an average age of 33 years old (SD = 10.86). In this group of people, we found out that 59% were single (5,523), 71% were women (6,693). Forty-six percentage were complying with lockdown procedures (4,286), 50% were partially complying (4,682), and 4% were not complying at all (393). The invitation to participate was open from April 24th to April 30th during the second stage of the pandemic in Mexico, in 2020, characterized by voluntary complete lockdown staying at home. Thus, we used a cross-sectional online survey design to assess mental health risk factors related to the COVID-19 pandemic. The survey was available on a WebApp designed by Linux^®, PHP^®, HTML^®, CSS^®, and JavaScript^®. We calculated descriptive and inferential analysis to describe the mental health average distribution as a function of the lockdown, binge drinking, and experience of abuse. To calculate the reliability and validation of the subscales, we used Cronbach's Alpha and Factor Loading. We run the confirmatory factor loading analysis, and we described the relationship between each latent variable and its item factor load, obtained through structural modeling equations, derived from 179 iterations and 207 parameters (t_[1,171] = 28,079.418, p < 0.001). We got a CFI of 0.947, a TLC of 0.940, an RMSEA of 0.049 (0.049–0.050), and an SRMR of 0.048.

Findings: The results indicated that reported attitudes such as avoidance, sadness, withdrawal, anger, and anxiety were associated with acute stress, which was linked to an anxiety condition caused by uncertainty about achieving or maintaining overall good health.

Discussion and Prospects: People in lockdown mentioned a sudden increase in alcohol consumption. They lived episodes of physical and emotional abuse, in contrast with those who stated that they did not go into lockdown or consume alcohol, or experienced abuse.

Limitations: Further studies should diagnose mental health conditions as part of the impact of COVID-19, ensure their follow-up, and assess the effect of providing remote psychological care. There is a need to explore methods to curb the increase in the number of people affected by post-traumatic stress disorder.

ICD-11 'mixed depressive and anxiety disorder' is clinical rather than sub-clinical and more common than anxiety and depression in the general population

Background

The new International Classification of Diseases was published in 2018 (ICD‐11; World Health Organization, 2018) and now includes ‘Mixed depressive and anxiety disorder’ (6A73: MDAD) designated as a mood disorder. This disorder is defined by symptoms of both anxiety and depression occurring more days than not, for a period of two weeks, and neither set of symptoms considered separately reaches a diagnostic threshold for either disorder. However, to date no study has examined the validity of these guidelines in a general population sample.

Methods

Using Goldberg et al.’s (2017) guidelines regarding measurement of depression and anxiety, this study used factor mixture modelling (FMM) to examine the validity of the ICD‐11 criteria of MDAD. Symptom endorsement rates are provided as well as demographic predictors and somatization outcomes.

Results

Fit indices suggested the two‐factor four‐class solution was the best balance between model complexity and model fit. The results did not support a class that is subsyndromal to both anxiety and depression. On the contrary, we suggest that there exists a ‘Comorbid’ class that represents endorsement of both anxiety and depression symptoms at a higher level when compared to both ‘anxiety’ and ‘depression’ groups. Demographic predictors, as well as somatization and functional impairment outcomes, provided support for this FMM solution.

Conclusions

The ‘Comorbid’ group was the largest symptomatic group and had the highest levels of both anxiety and depression symptoms. Importantly, this group was larger than either the ‘anxiety’ or ‘depression’ group and was associated with high levels of functional impairment and somatization.

Factors Differentiating Rural and Urban Population in Determining Anxiety and Depression in Patients with Chronic Cardiovascular Disease: A Pilot Study

The aim of this cross-sectional study was to analyze selected variables differentiating rural from urban populations, as well as identify potentially increased levels of depression and anxiety in patients with chronic cardiovascular disease. The study was carried out in 193 patients. The study used the Camberwell Assessment of Need Short Appraisal Schedule (CANSAS), the Health Behavior Inventory Questionnaire (HBI), the WHOQOL-BREF Quality of Life Questionnaire, and the Hospital Anxiety and Depression Scale-Modified Version (HADS-M). Spearman's rank correlation coefficient test and logistic regression were used for analyses. In rural patients, we observed a relationship between anxiety and age (1/OR = 1.04; 95% CI: 0.91-0.99), the assessment of satisfied needs (1/OR = 293.86; 95% CI: 0.00001-0.56), and quality of life (QoL) in physical (OR = 1.56; 95% CI: 1.11-2.33), social (1/OR = 1.53; 95% CI: 0.04-0.94), and environmental domains (OR = 1.67; 95% CI: 1.06-3.00), as well as between depression and QoL in physical (1/OR = 1.39; 95% CI: 0.50-0.97) and psychological (OR = 1.37; 95% CI: 1.01-1.93) domains. In city patients, we observed a relationship between the drug and Qol in the physical (1/OR = 1.25; 95% CI: 0.62-0.98) and psychological (OR = 1.49; 95% CI: 1.13) domains. Younger patients living in a rural area with a lower assessment of met needs, a higher level of QoL in physical and environmental domains, and a lower social domain, as well as patients living in a city with a lower QoL in the physical domain and a higher psychological domain, have a greater chance of developing anxiety and depressive disorders.

Differences in Health-Related Quality of Life Predictors in People Living With HIV With and Without Diabetes

Diabetes is one of the most common comorbid conditions in people living with HIV (PLWH). Diabetes may affect health-related quality of life (HRQoL) for PLWH because they experience more symptoms, are prescribed more medications, and are required to do self-care activities. The purpose of our study was to compare predictors of the HRQoL for PLWH with and without diabetes. The study was a secondary analysis of data from the Center for AIDS Research Network of Integrated Clinical Systems cohort using multiple regression. Significant differences were found between PLWH with and without diabetes. The significant predictors of HRQoL for PLWH-alone were depression, anxiety, medication adherence, physical activity, smoking, and age. For PLWH with diabetes, the only significant predictors of HRQoL were anxiety and depression.

Mental health problems among healthcare workers involved with the COVID-19 outbreak

OBJECTIVE

The mental health problems and perceived needs of healthcare workers involved with coronavirus disease (COVID-19) may vary due to individual and contextual characteristics. The objective of this study was to evaluate healthcare workers' mental health problems during the common COVID-19 exposure scenario in Mexico, comparing those on the frontline with other healthcare workers according to gender and profession, determining the main risk factors for the most frequent mental health problems.

METHODS

A cross-sectional online study was conducted with a non-probabilistic sample of 5,938 Mexican healthcare workers who completed brief screening measures of mental health problems and ad hoc questions about sociodemographic professional characteristics, conditions related to increased risk of COVID-19 infection, life stressors during the COVID-19 emergency, and perceived need to cope with COVID-19.

RESULTS

The identified mental health problems were insomnia, depression, and posttraumatic stress disorder (PTSD), all of which were more frequent in frontline healthcare workers (52.1, 37.7, and 37.5%, respectively) and women (47.1, 33.0 %, and 16.3%, respectively). A lack of rest time was the main risk factor for insomnia (OR = 3.1, 95%CI 2.6-3.7, p ≤ 0.0001). Mourning the death of friends or loved ones due to COVID-19 was the main risk factor for depression (OR = 2.2, 95%CI 1.8-2.7, p ≤ 0.0001), and personal COVID-19 status was the main risk factor for PTSD (OR = 2.2, 95%CI 1.7-2.9, p ≤ 0.0001).

CONCLUSION

The most frequent mental health problems during the common exposure scenario for COVID-19 in Mexico included the short-term psychological consequences of intense adversity. A comprehensive strategy for preventing mental health problems should focus on individuals with cumulative vulnerability and specific risk factors.

The blurred line between anxiety and depression: hesitations on comorbidity, thresholds and hierarchy

The delineation of anxiety and depression as well as the relation between anxiety and depression are still subject of debate. Many patients suffering from depression also suffer from anxiety, and many patients with anxiety suffer or will suffer from depression. The co-occurrence or co-morbidity is higher than what could be expected based on their respective prevalences, and even pushed some authors to call it cothymia. This epidemiological and clinical reality results in many conceptual hesitations. We first will summarize how the different (versions of the) classification systems do not seem to have been successful in their attempts to delineate the blurred line between depression and anxiety, before questioning whether a dialogue with a more phenomenological or psychopathological approach could be helpful in understanding the articulation between both affective phenomena, as well as in bridging neurobiological research and clinical practice.

A systematic review of validated screening tools for anxiety disorders and PTSD in low to middle income countries

BACKGROUND

Anxiety and post-traumatic stress disorder (PTSD) contribute significantly to disability adjusted life years in low- to middle-income countries (LMICs). Screening has been proposed to improve identification and management of these disorders, but little is known about the validity of screening tools for these disorders. We conducted a systematic review of validated screening tools for detecting anxiety and PTSD in LMICs.

METHODS

MEDLINE, EMBASE, Global Health and PsychINFO were searched (inception-April 22, 2020). Eligible studies (1) screened for anxiety disorders and/or PTSD; (2) reported sensitivity and specificity for a given cut-off value; (3) were conducted in LMICs; and (4) compared screening results to diagnostic classifications based on a reference standard. Screening tool, cut-off, disorder, region, country, and clinical population were extracted for each study, and we assessed study quality. Accuracy results were organized based on screening tool, cut-off, and specific disorder. Accuracy estimates for the same cut-off for the same screening tool and disorder were combined via meta-analysis.

RESULTS

Of 6322 unique citations identified, 58 articles including 77 screening tools were included. There were 46, 19 and 12 validations for anxiety, PTSD, and combined depression and anxiety, respectively. Continentally, Asia had the most validations (35). Regionally, South Asia (11) had the most validations, followed by South Africa (10) and West Asia (9). The Kessler-10 (7) and the Generalized Anxiety Disorder-7 item scale (GAD-7) (6) were the most commonly validated tools for anxiety disorders, while the Harvard Trauma Questionnaire (3) and Posttraumatic Diagnostic Scale (3) were the most commonly validated tools for PTSD. Most studies (29) had the lowest quality rating (unblinded). Due to incomplete reporting, we could meta-analyze results from only two studies, which involved the GAD-7 (cut-off ≥10, pooled sensitivity = 76%, pooled specificity = 64%).

CONCLUSION

Use of brief screening instruments can bring much needed attention and research opportunities to various at-risk LMIC populations. However, many have been validated in inadequately designed studies, precluding any general recommendation for specific tools in LMICs. Locally validated screening tools for anxiety and PTSD need further evaluation in well-designed studies to assess whether they can improve the detection and management of these common disorders.

Symptoms of anxiety and depression in children with developmental coordination disorder: a systematic review

OBJECTIVE

To find evidence of the symptoms of anxiety/depression in children with developmental coordination disorder as compared to their typically developing peers at both the group and individual level, and to identify how many different tools are used to measure anxiety and/or depression.

METHODS

Electronic searches in eight databases (PubMed/MEDLINE, Scopus, Web of Science, ERIC, PsycINFO, Embase, SciELO and LILACS), using the following keywords: 'Developmental Coordination Disorder,' 'Behavioral Problems,' 'Child,' 'Anxiety,' 'Depression,' 'Mental Health,' and 'Mental Disorders.' The methodological quality was assessed by Newcastle-Ottawa Scale adapted for cross-sectional studies and the NOS for cohort studies. The studies were classified as low, moderate, or high quality. To provide clinical evidence, the effect size of the symptoms of anxiety and depression was calculated for each study.

RESULTS

The initial database searches identified 581 studies, and after the eligibility criteria were applied, six studies were included in the review. All studies were classified as being of moderate to high quality, and the effect sizes for both anxiety and depression outcomes were medium. The evidence indicated that all of the assessed studies presented more symptoms of anxiety and depression in children with developmental coordination disorder than in their typically developing peers. On the individual level, this review found children with clinical symptoms of anxiety in 17-34% (developmental coordination disorder) and 0-23% (typically developing), and of depression in 9-15% (developmental coordination disorder) and 2-5% (typically developing) of the children.

CONCLUSIONS

Children with developmental coordination disorder are at higher risk of developing symptoms of anxiety and depression than their typically developing peers.

Factorial invariance of a computerized version of the GAD-7 across various demographic groups and over time in primary care patients

BACKGROUND

The Generalized Anxiety Disorder 7-item scale (GAD-7) is commonly used by clinicians and researchers to screen for anxiety disorders and to monitor anxiety symptoms in primary care. However, findings regarding its factor structure are mixed, with most studies reporting a best-fitting for a one-factor structure, whereas others indicate a two-factor model. To be valid for comparisons, the GAD-7 should measure the same latent construct with the same structure across groups and over time. We aimed to examine the best-fit factor structure model of the GAD-7 among primary care patients and to evaluate its measurement invariance.

METHODS

A total of 1255 patients completed the computerized version of GAD-7 and a subsample of 238 cases was assessed at the 3-month follow-up. A confirmatory factor analysis (CFA) was performed and analyses of multiple-group invariance were also conducted to determine the extent to which the factor structure was comparable across various sociodemographic groups and over time.

RESULTS

The results showed that both a one- and two-factor structure (representing somatic and cognitive-affective components) were invariant across sociodemographic groups and over time. The two-factor structure provided the best model fit.

LIMITATIONS

Results cannot be generalized to all primary care patients, as only patients whose general practitioners consider them to suffer emotional disorders were included.

CONCLUSIONS

Our study supports the reliability and validity of the one- and two-factor model of the GAD-7, both for screening purposes and for monitoring response to treatment.

Prevalence of depression and anxiety and their association with cardiovascular risk factors in Northeast Brasil primary care patients

SUMMARY BACKGROUND: Depression and anxiety disorders (DAD) are the most prevalent mental health conditions worldwide. Among the adult population served in basic care, it is estimated that depression affects about 14.3% of these individuals worldwide, and between 21.4% and 31% in Brasil. Anxiety affects up to 33.7% of the population during their lifetimes. OBJECTIVES: estimate the prevalence proportions of DAD among patients in a municipality in Northeast Brasil and study the association between DAD and cardiovascular risk factors. METHODS: a cross-sectional study with the medical records of patients from primary care centers in Jaboatão dos Guararapes, Pernambuco. Patients aged ≥ 18 years and regularly followed-up were included. Exclusion criteria: a history of traumatic brain injury, alcohol or drug abuse, previous stroke, medical conditions or medications that mimic DAD symptoms. Subjects were divided into two groups depending on the presence or absence of DAD, and cardiovascular risk factors were compared between groups. RESULTS: A total of 1030 subjects were initially included, of whom 215 (20%) were excluded. No-DAD subjects had more history of myocardial infarction and alcoholism. The prevalence of depression was 10.3%, anxiety disorder was 27.1%, and mixed DAD represented 4.5%. There was a significant association between DAD and hypertension (OR = 2.11; 95%CI: 1.16 –3.84; p=0.01), obesity (OR = 4.47; 95%CI: 1.74 –11.46; p=0.002), and hyperlipidemia (OR = 3.88; 95%CI: 1.81-8.3; p<0.001). CONCLUSION: DAD were associated with an increased risk for arterial hypertension, obesity, and hyperlipidemia.

Dimensional analysis of depressive, anxious and somatic symptoms presented by primary care patients and their relationship with ICD-11 PHC proposed diagnoses

BACKGROUND

A study conducted as part of the development of the Eleventh International Classification of Mental Disorders for Primary Health Care (ICD-11 PHC) provided an opportunity to test the relationships among depressive, anxious and somatic symptoms in PHC.

METHOD

Primary care physicians participating in the ICD-11 PHC field studies in five countries selected patients who presented with somatic symptoms not explained by known physical pathology by applying a 29-item screening on somatic complaints that were under study for bodily stress disorder. Patients were interviewed using the Clinical Interview Schedule-Revised and assessed using two five-item scales that measure depressive and anxious symptoms. Structural models of anxious-depressive symptoms and somatic complaints were tested using a bi-factor approach.

RESULTS

A total of 797 patients completed the study procedures. Two bi-factor models fit the data well: Model 1 had all symptoms loaded on a general factor, along with one of three specific depression, anxiety and somatic factors [x2 (627) = 741.016, p < 0.0011, RMSEA = 0.015, CFI = 0.911, TLI = 0.9]. Model 2 had a general factor and two specific anxious depression and somatic factors [x2 (627) = 663.065, p = 0.1543, RMSEA = 0.008, CFI = 0.954, TLI = 0.948].

CONCLUSIONS

These data along with those of previous studies suggest that depressive, anxious and somatic symptoms are largely different presentations of a common latent phenomenon. This study provides support for the ICD-11 PHC conceptualization of mood disturbance, especially anxious depression, as central among patients who present multiple somatic symptoms.

Diagnostic consequences of a new category of anxious depression and a reduced duration requirement for anxiety symptoms in the ICD-11 PHC

BACKGROUND

A new diagnosis of anxious depression (AD), characterized by both depressive and anxious symptoms at case level, has been proposed for the classification of mental disorders for primary care for ICD-11 (ICD-11 PHC). The ICD-11 PHC proposes a duration requirement for anxiety symptoms of 2 weeks, in line with the requirement for depressive symptoms. This study examined diagnostic assignment under ICD-11 PHC as compared to the previous classification, the ICD-10 PHC, and the relationship of anxiety duration to disability and suicidal ideation.

METHODS

Primary care physicians in five countries referred patients based on either perceived psychological distress or distressing somatic symptoms to a research assistant who administered a computer-guided diagnostic interview. Complete data were obtained for 2279 participants.

RESULTS

Under ICD-11 PHC 47.7% participants received a diagnosis of AD and had greater disability than other diagnostic groups. Under ICD-10 PHC, in addition to meeting requirements for depressive episode, most of these patients met requirements for either generalized anxiety disorder (41.5%) or mixed anxiety and depressive disorder (45.4%). One third of individuals diagnosed with AD had anxiety durations between 2 weeks and 3 months and presented as much disability and suicidal ideation as individuals with longer anxiety durations.

LIMITATIONS

The study was not designed to establish prevalence of these conditions.

CONCLUSION

The proposed ICD-11 PHC encourages early identification and management of significant anxiety symptoms in primary care, particularly when these co-occur with depression. This study provides support for the clinical relevance of these symptoms and the importance of early identification.

Tree analysis modeling of the associations between PHQ-9 depressive symptoms and doctor diagnosis of depression in primary care

BACKGROUND

The aim of this study was to explore the relationship between patient self-reported Patient Health Questionnaire-9 (PHQ-9) symptoms and doctor diagnosis of depression using a tree analysis approach.

METHODS

This was a secondary analysis on a dataset obtained from 10 179 adult primary care patients and 59 primary care physicians (PCPs) across Hong Kong. Patients completed a waiting room survey collecting data on socio-demographics and the PHQ-9. Blinded doctors documented whether they thought the patient had depression. Data were analyzed using multiple logistic regression and conditional inference decision tree modeling.

RESULTS

PCPs diagnosed 594 patients with depression. Logistic regression identified gender, age, employment status, past history of depression, family history of mental illness and recent doctor visit as factors associated with a depression diagnosis. Tree analyses revealed different pathways of association between PHQ-9 symptoms and depression diagnosis for patients with and without past depression. The PHQ-9 symptom model revealed low mood, sense of worthlessness, fatigue, sleep disturbance and functional impairment as early classifiers. The PHQ-9 total score model revealed cut-off scores of &gt;12 and &gt;15 were most frequently associated with depression diagnoses in patients with and without past depression.

CONCLUSIONS

A past history of depression is the most significant factor associated with the diagnosis of depression. PCPs appear to utilize a hypothetical-deductive problem-solving approach incorporating pre-test probability, with different associated factors for patients with and without past depression. Diagnostic thresholds may be too low for patients with past depression and too high for those without, potentially leading to over and under diagnosis of depression.

Factorial structure of the Patient Health Questionnaire-9 as a depression screening instrument for university students in Cartagena, Colombia

Previous studies on the factorial structure of the Patient Health Questionnaire (PHQ-9) have yielded divergent results, and there is no consensus on which factorial structure provides a more adequate fit. In Colombia, no precise method to estimate the factorial structure of the PHQ-9 has been used. The purpose of this study is to evaluate the factorial structure of the PHQ-9 as a depression screening tool in university students of Colombia from a model of two factors previously studied. The PHQ-9 was applied to 550 health science university students. A factorial confirmatory analysis was carried out using a structural equations model and invariance analysis. The model with one somatic factor and one non-somatic factor, achieved a better fit with invariance by gender. The PHQ-9 used as a depression screening tool used in university students in Cartagena revealed two factors, one somatic and one non-somatic with measurement invariance by gender.

Studying ICD-11 Primary Health Care bodily stress syndrome in Brazil: do many functional disorders represent just one syndrome?

Objective:

Disorders characterized by “distressing unexplained somatic symptoms” are challenging. In the ICD-11 Primary Health Care (PHC) Guidelines for Diagnosis and Management of Mental Disorders (ICD-11 PHC), a new category, bodily stress syndrome (BSS), was included to diagnose patients presenting unexplained somatic symptoms. The present study investigated the association of BSS with anxiety, depression, and four subgroups of physical symptoms in a Brazilian primary health care (PHC) sample.

Methodology:

As part of the international ICD-11 PHC study, 338 patients were evaluated by their primary care physicians, followed by testing with Clinical Interview Schedule (CIS-R) and World Health Organization Disability Assessment Schedule, Version 2.0 (WHODAS 2.0). BSS was diagnosed in the presence of at least three somatic symptoms associated with incapacity. The association between anxiety, depression, and four subgroups of physical symptoms with being a BSS case was analyzed.

Results:

The number of somatic symptoms was high in the overall sample of 338 patients (mean = 8.4), but even higher in the 131 BSS patients (10.2; p < 0.001). Most BSS patients (57.3%) had at least three symptoms from two, three, or four subgroups, and these were associated with anxiety and depression in 80.9% of these patients. The symptom subgroup most strongly associated with “being a BSS” case was the non-specific group (OR = 6.51; 95%CI 1.65-24.34), followed by musculoskeletal (OR = 2,31; 95%CI 1.19-4.72).

Conclusion:

Somatic symptoms were frequent in a sample of PHC patients in Brazil. In the present sample, one third were BSS cases and met the criteria for at least two symptom subgroups, supporting the hypothesis that different functional symptoms are related to each other.

Generalized anxiety disorder and associated factors in adults in the Amazon, Brazil: A population-based study

BACKGROUND

The purpose of this study was to assess the prevalence and associated factors of generalized anxiety disorder (GAD) in adults using the seven-item GAD scale (GAD-7) and to evaluate the properties of the two-item (GAD-2) as a population screening tool.

METHODS

We carried out a cross-sectional population-based study in the Manaus Metropolitan Region in 2015, Brazil. Adults aged 18 years or more were eligible to participate. We performed probabilistic three-phase sampling and collected sociodemographic and clinical variables. Descriptive statistics and a Poisson regression with robust variance with corrections for complex sampling were used. The accuracy of GAD-2 was assessed using GAD-7 as the gold standard.

RESULTS

We included 4001 participants. The prevalence of GAD was 8.4% (95% confidence interval 7.6-9.4%) and was significantly associated with self-reported poor health status and presenting depressive symptoms (p < 0.01). GAD-2 sensitivity was 63.9%, and its specificity was 97.4%.

LIMITATIONS

Because of the cross-sectional design of the study, the results are prone to reverse causality and recall bias. The surveyed people were not questioned about their medical diagnosis of anxiety, access to mental health services, or alcohol, tobacco or other drug use. The screening tools were not validated in the Brazilian or Amazon population.

CONCLUSION

About eight in 100 adults living in Manaus presented GAD, and it is more prevalent among people with a poorer health status and depression. Because of its low sensitivity, GAD-2 is not useful as a screening tool.

A computerized version of the Patient Health Questionnaire-4 as an ultra-brief screening tool to detect emotional disorders in primary care

BACKGROUND

The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief self-report consisting of a 2-item depression scale (PHQ-2) and a 2-item anxiety scale (GAD-2). The aim of the present study is to determine the psychometric properties of a computerized version of the PHQ-4 used to detect emotional disorders (anxiety and depression) in the primary care setting.

METHOD

A total of 1052 patients with suspected anxiety, depression, or somatic symptoms were recruited from 28 primary care centres participating in the PsicAP trial and completed the full version of the computerized PHQ. In addition, 178 of these patients also underwent in clinical interviews as a gold standard.

RESULTS

Confirmatory factor analyses showed very good fit indices for a two-factor solution. This model was structurally invariant among the various age and gender groups and internal consistency was acceptable (PHQ-4; α = .83, PHQ-2; α = .86, and GAD-2; α = .76). The best cut-off points to obtain high sensitivity values was 3, on both the PHQ-2 (major depressive disorder) and the GAD-2 (generalized anxiety disorder). The criterion validity (sensitivity and specificity) for the PHQ-2 were .90 and .61 and for the GAD-2, .88 and 0.61.

LIMITATIONS

The study was not designed as a prevalence study. Therefore, does not contain information on patients whose general practitioners do not consider them to suffer emotional disorders.

CONCLUSION

This is the first study to provide evidence for the reliability and validity of a computerized version of the PHQ-4. This computerized tool can be used to detect depression and anxiety in a primary care setting.

Patients with anxious depression: overview of prevalence, pathophysiology and impact on course and treatment outcome

PURPOSE OF REVIEW

Major depressive disorder with a comorbid anxiety disorder or with significant anxiety symptoms (here called anxious depression) is common and has been associated with poor clinical course trajectories. However, various dichotomous as well as dimensional definitions have been used to label anxious depression and it remains unclear to which extent these result in inconsistent findings. This review provides an overview of recent literature on the impact of anxiety in depressed patients on clinical course trajectories, treatment outcomes, and underlying neurobiological dysregulations.

RECENT FINDINGS

Anxious depression seems associated with poorer clinical course trajectories and treatment nonresponse as compared with 'pure' depression, regardless of which definition is used. Recent studies have attempted to determine specific efficacy of novel pharmacological treatments for anxious depressed patients, but have not been conclusive because of the insufficient number of studies and differences in definitions and assessment of anxious depression. Neurobiology studies suggest that anxious depression is associated with increased immune dysregulation, more cortical thinning, and corticolimbic dysfunctions as compared with 'pure' depression.

SUMMARY

Anxious depression appears to be a common and clinically relevant subtype of depression as it predicts poorer course trajectories. As populations with anxious depression may benefit from specific treatment regimens, further research is necessary to better delineate its definition and neurobiology. The relatively new Diagnostic and Statistical Manual of Mental Disorders-5 anxious distress specifier is a welcome development and should be further investigated and compared against other anxiety constructs.

Primary care physicians' use of the proposed classification of common mental disorders for ICD-11

BACKGROUND

The World Health Organization is revising the classification of common mental disorders in primary care for ICD-11. Major changes from the ICD-10 primary care version have been proposed for: (i) mood and anxiety disorders; and (ii) presentations of multiple somatic symptoms (bodily stress syndrome). This three-part field study explored the implementation of the revised classification by primary care physicians (PCPs) in five countries.

METHODS

Participating PCPs in Brazil, China, Mexico, Pakistan and Spain were asked to use the revised classification, first in patients that they suspected might be psychologically distressed (Part 1), and second in patients with multiple somatic symptoms causing distress or disability not wholly attributable to a known physical pathology, or with high levels of health anxiety (Part 2). Patients referred to Part 1 or Part 2 underwent a structured diagnostic interview. Part 3 consisted of feedback from PCPs regarding the classification.

RESULTS

In Part 1, anxious depression was the most common disorder among referred patients. PCPs assigned the highest severity ratings to anxious depression, and the next highest to current depression; current anxiety was rated as least severe. Considerable overlap was found between bodily stress syndrome (BSS) and health anxiety (HA). The psychiatric interview recorded higher rates of mood and anxiety disorders diagnoses among patients with BSS than did PCPs. PCPs' satisfaction with the revised classification was high.

CONCLUSIONS

Results generally supported the inclusion of the new categories of anxious depression, BSS and HA for ICD-11 PHC and suggested that PCPs could implement these categories satisfactorily.
